DAGUERREOTYPE-CASE.

Specification forming part of Letters Patent No. 9,611, dated March 8,1853; Reissued February 9, 1869, No. 3,291.

To all whom it may concern:

Be it known that I, J. F. MASCI-IER, of the city and county ofPhiladelphia and State of Pennsylvania, have invented a new and usefulImprovement in Daguerreotype- Cases, whereby the cases may be convertedinto stereoscopes; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theannexed drawings, making a part of this specification, in which Figure1, is a perspective view of my improved daguerreotype case. Fig. 2, is aside elevation of ditto. Fig. 3, is a vertical section of ditto, thecase being closed and bisected through its center.

Similar letters of reference indicate corresponding parts in each of theseveral figures.

The nature of my invent-ion consists in constructing a daguerreotypecase with an adjustable flap or supplementary lid, said flap or lidbeing within the case and arranged as will behereafter described andhaving two ordinary lenses placed in it. The case contains two picturesor daguerreotypes. A daguerreotype being placed opposite each of thelenses in the flap or lid when the lid is properly adjusted. By thisarrangement a perfect stereoscope is obtained and the daguerreotypes bybinocular vision are apparently formed into a solid figure like life.

To enable others skilled in the art to make and use my invention, I willproceed to clescribe its construction and operation.

A, represents the bottom or back of the case which contains twodaguerreotypes E, E, placed side by side as seen in Fig. 1.

B, is the top or lid connected as usual to the back A, by hinges (a). Onthe inner side of the top or lid B, there is attached by [FIRST PRINTED1913.]

hinges (b) a flap or supplementary lid 0, said flap or lid whendepressed fitting in a cavity in the top or lid B, as seen in Fig. 3.This flap or supplementary lid has two lenses D, D, placed in it eachlens being directly opposite a daguerreotype, see Fig. 1. Now when theflap or supplementary lid 0, is raised in the position as seen in Fig.1, and the back A, also elevated as shown a daguerreotype will beopposite each lens D, and a perfect stereoscope is formed and by lookingthrough the lenses D, D, an eye being applied to each; the twodaguerreotypes will appear as one; solid and life like.

The flap or supplementary lid C, is secured when raised to its properposition by a. small hook or catch (0) see Fig. 1.

' When it is designed to close the case, the hook or catch (0) isunfastened; the flap C, depressed within the lid B, and the lid B, andback A, pressed together as seen in Fig. 3, the whole forming a case asportable as the ordinary daguerreotype cases.

I do not claim the invention of a stereoscope, for that has beenpreviously discovered. But

What I claim as new, and desire to secure by Letters Patent, is

Constructing a daguerreotype case with an adjustable flap orsupplementary lid C, said flap or lid G, being within the case andhaving two ordinary lenses D, D, placed in it, by which, upon adjustingthe flap or lid as shown, a stereoscope is formed of the case and thetwo daguerreotypes E, E, by binocular vision are apparently formed intoa life like figure.
